Zeolitic imidazolate frameworks (ZIFs), a subclass of metal organic frameworks, are built of tetrahedral metal ions bridged by imidazolates. They have permanent porosity and relatively high thermal and chemical stability, which make them attractive candidates for many industrial applications. In recent years, significant progress has been made in developing ZIFs into membranes and thin films fo...

A palladium composite membrane was prepared by electroless plating on oxidized porous stainless steel support (ox-PSS). Hydrogen permeation flux through this composite membrane was measured in the temperature range of 574-674K and the pressure difference of two sides of membrane up to 90kPa. A simplified resistance model was employed to analyze the permeation behavior of hydrogen through Pd/ox-...

3D printed nanofiltration (NF) composite membranes with surface patterns minimising the impact of concentration polarisation (CP) are presented here for first time. The consist a NF polydopamine?coated polyvinylidene fluoride (PVDF/PDA) selective layer on asymmetric wavy (patterned) support. result is membrane pure water permeance 14 ± 2 LMH bar ? 1 and molecular weight cut-off ?550 Da, measure...

Individual molecules with intrinsic porosity, such as porous organic cages (POCs), have significant potential to improve the performance of a variety separations media. An exemplar application is blending POCs polymers make molecularly-mixed composite membranes (MMCMs). The intimate interaction between individual cage and polymer chains results in “solid-solution” that avoids longstanding inter...
